WILLIAM BOVILL, OF CHICAGO, ILLINOIS.

FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N0. 754,416, dated Marchv15, 1904.

Application filed November 5,1903. Serial No. 179,950. (No model.)

T0 all whom/ it may concern:

Be it known that I, WILLIAM BovILL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful vImprovements in Fountain-Pens; and I dodeclare the following to be a full, clear, and eX- act description ofthe invention, such asvvill enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in fountain-pens, andparticularly to means oarried by the pen, whereby the same may bequickly and easily iilled.

A further object is to provide such means which will be simple, strong,eflicient, and' capable of being collapsed or reduced in size when notin use, thereby permitting the penholder to be made in compact form.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described and particularly pointed out in theappended claims.

v In the accompanying drawings, Figure 1 is a longitudinal sectionalview of the barrel or casing of a pen embodying the invention. Figs. 2and 3 are similar views of the end caps of the barrels. Fig. 4 is a viewin longitudinal section and elevation, respectively, of the piston andits xed stem or inner rod-section. Fig. 5 is a longitudinal section ofthe outer tubular section of the piston-rod. Fig. 6 is a view similar toFig. 1, showing the piston applied and drawn out for filling the pen;and Fig. 7 is an enlarged cross-sectional View taken on line 7 7 of Fig.6.

Referring to the drawings more particularly, l denotes a fountain-penwhich may be of the usual or any suitable construction, consisting of abarrel portion 2 and a pen-point 3, which when not in use is adapted tobe inclosed by the usual removable cap 4.

Within the barrel 2 is arranged a piston 5, which-is adapted to closelyfit within the inner walls of said barrel. The piston 5 is provided witha two-part piston-rod 6, consisting of an inner section 7, which isfixed to the piston at its inner end and is provided near its outer endwith a laterally-projecting pin or lug 8.

On or around the inner section is arranged an outer tubular section9,open at each end and provided with a longitudinal slot 10,whichextends from the outer end of the tube to within a short distance 0f theinner end of the same, at which point said slot is formed with aright-angular offset or recess 12. When the two sections of thepiston-rod are assembled, the inner section 7 is adapted to slide withinthe outer section, with lug 8 engaging the slot in the same. When saidsectionsl have been extended to their full length, the outer section isgiven a slight turn, which will engage the recess l2 with the lug 8,thereby locking the parts against telescopic movement.

The combined length of the two sections of the piston-rod is equal to'or slightly greater than the length of the interior of the barrel 2, sothat when said sections are in their extended positions and locked thepiston 5 may be pushed into the pen end of the barrel and then withdrawnto create a sucking action after the manner of a syringe and by whichmovement or action of the piston the pen may be filled upon theinsertion of the pen end of the same into a receptacle containing ink.

A stop I3 is arranged at the end of the barrel 2 opposite the pen endthereof, by which the outward movement of the piston 5 is limited,thereby preventing the piston from being entirely withdrawn. The stop 13may be of any suitable construction, but is here shown as an annularring or collar arranged within the barrel 2 at the outer end of the sameand removably secured thereto by means of pins or screws 14.

The outer end of the tubular section of the piston-rod is provided witha head or enlargement 15, by which the same may be operated. When thesections of the piston-rods have been telescoped together after havingdrawn the piston outwardly to iill the pen, they may be inclosed by acap 16, which is adapted to iit over the end of the barrel, said endbeing reduced to form a shoulder or seat 17, against which the end ofthe cap abuts and which prevents the same from being forced too far ontosaid barrel.

From the foregoing description, taken in connection with theaccompanying drawings,

IOO

the construction and operation of the invention will be readilyunderstood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction 'may be resorted to Without departing from the principle orsacricing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a fountain-pen, the combination with the barrel or body of thesame, of a piston arranged to reciprocate therein, a piston-rodcomprising an inner section xed to said piston, an outer tubular sectionslidably mounted on said inner section, a pin-and-slot connectionbetween said sections and means whereby the same may be locked inextended positions,

on said inner section and having a longitudinal slot formed therein toengage said lpin or lug, and a right-angularly-formed recess comlug, aright-angularly-forrned recess communicating with said slot and withwhich said pin or stud may be engaged to lock said sections againsttelescopic movement, a ring or collar removably secured 1n the outer endot said pen-barrel to limit 'the .outward movement of said piston, andmeans'for removably securing said collar within said barrel,substantially as described.

In testimony whereof I have 'hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM BOVILL.
